"The Real Housewives of New Jersey" star Teresa Giudice and her husband, Joe, have answered to fraud charges brought against them.

The couple were arraigned in federal court on Wednesday, reported New Jersey's Star-Ledger. They entered a not-guilty plea in front of U.S. District judge Esther Salas in Newark at 2:30 p.m. ET.

In July, the Bravo stars were charged with 39 counts, including mail and wire fraud, bank fraud, bankruptcy fraud, making false statements on loan applications and failure to file tax returns. The Giudices were later released on a $500,000 bond, but didn't enter a plea at the time.

The conspiracy to commit mail and wire fraud count carries a maximum potential penalty of 20 years in prison and a $250,000 fine. The bank fraud and loan application fraud counts each carry a maximum potential penalty of 30 years in prison and a $1 million fine. The bankruptcy fraud counts each carry a maximum penalty of five years in prison and a $250,000 fine. The failure to file a tax return counts each carry a maximum penalty of one year in prison and a $100,000 fine.

Also, Joe, is at risk of being deported to Italy if found guilty. The 43-year-old moved to the U.S. as a child but never became a citizen.

In 2009, the couple filed for bankruptcy, but prosecutors said they concealed businesses, property and lied about Teresa's income.
